How to make plant-based pesticides by yourself?
This article provides a detailed explanation on the aspects of home flower cultivation, including how to make plant-based pesticides. Let's take a look together!
Plant-based pesticides can be made from locally available materials, are easy to produce, and are free from harm, residue, and pollution, providing good control over common diseases and pests in home gardening.
Main materials include:
(1) Garlic juice. Take 250 grams of purple-skinned garlic, soak in water for a moment, mash and extract the juice, dilute with water 10-20 times and spray, which can control pests such as aphids, spider mites, and scale insects, and is also effective against powdery mildew and gray mold. Pouring this liquid into the potting soil can control nematodes and earthworms.
(2) Chili water. Take 50 grams of red chili peppers, boil with 1000 grams of clear water for 15 minutes, filter and spray the supernatant, which can control pests such as whitefly, aphids, spider mites, and stink bugs.
(3) Tobacco leaf soak. Take 50 grams of tobacco leaves (double if using tobacco stems or cigarette papers), add 1500 grams of clear water, soak for 24 hours, knead repeatedly with hands and filter, then add 0.1%-0.2% neutral laundry detergent and spray, which can control pests such as aphids, spider mites, leafhoppers, whiteflies, thrips, stink bugs, leaf-rolling caterpillars, and other leaf-eating pests.
(4) Wormwood water. Take 500 grams of wormwood, boil with 2500-4000 grams of clear water for half an hour, filter and water the plants, which can control underground pests such as the ground elder (H), and also control damping-off disease. A 10-fold dilution of wormwood water can control aphids, spider mites, and soft-bodied pests.
(5) Tea seed cake. Crush the tea seed cake, soak in a small amount of hot water for 24 hours, filter out the residue, dilute with 30-40 times water and spray, which can control pests such as aphids, planthoppers, and snails. Spraying with a 40-fold dilution is also effective against rust disease. Additionally, chopped and mashed materials such as scallions, chives, ginger, onions, Sichuan peppercorns, peach leaves, castor beans, ginkgo leaves, plantain, and datura, soaked and filtered in water and then sprayed or applied to the soil, can also control many common pests.
Attention should be paid to safety during the production process and the materials should be kept out of reach of children!
